I want to explore a hypothetical to understand your perspective a bit better.

Let's say the only thing she said on the topic was that she thought trans women shouldn't be allowed in competitive women sports because they probably have a biological advantage over non-trans women, or at least that there's insufficient evidence that they do not.

Would this be enough to justify the label of "despicable" in your mind?

No, it's not. But that's a pretty ridiculous hypothetical, very few people who aren't actually transphobic care so much and spend so much time griping about such a miniscule issue.

You keep saying this but that isn't close to the only thing she said on the topic nor was it the genesis of any of the drama surrounding the issue. If you haven't read more on the issue it purely down to ignorance but if you have its not an honest portrayal of the issues.

No, in the first sentence I clearly stated that it was a hypothetical. I wanted to see if that particular subset of what she has said is enough to classify her as "despicable".
